The leaf essential oil obtained from Miramar was dominated by oxygenated sesquiterpenes
contains many chemical components, such as alkaloids, sugar, sesquiterpenes
, lipids, and coumarin materials.
54 Oxygenated sesquiterpenes
(OS) 19 (E)-Nerolidol 1567 n.
All ethanol extracts showed the different intensity of brown colour ranging from deep brown to light brown indicating the presence of mono-terpenes and sesquiterpenes
(essential oils), di-and triterpenoids (gums and resins), Tetraterpenoids (carotenoids, xanthophylls and carotenoic acids) and polyterpenoid is the rubber (Sameeno, 2007; and Raaman, 2006).
The slight variation reported in the number of volatile compounds was belonging to aldehydes, ketones, oxygenated monoterpenes, sesquiterpene
hydrocarbons and oxygenated sesquiterpenes
Mints oils are rich of monoterpenes and sesquiterpenes
that are important in food chemistry, chemical ecology and pharmaceutical industry .
It has been shown that sesquiterpenes
from Celastraceae are specific modulators of P-gps (Mufioz-Martinez et al.
These 35 chemical constituents covered a wide range of acids, alkenes, alcohols, aromatics, benzenes, esters, heterocyclics, ketones, monoterpenoids, monoterpene alcohols and sesquiterpenes
A total of fourteen compounds were identified which include aromatic, sesquiterpenes
, furocoumarins, sterols, fatty acid and their methyl esters.
Many secondary metabolites derived from plants, such as drimanes sesquiterpenes
, are present in species of the genus Drimys and exhibit a wide variety of biological activities, including leishmanicidal (CORREA et al.
Melissa officinalis extracts contain a range of phytochemicals including phenolic acids, flavonoids, sesquiterpenes
, monoterpenes and triterpenes with recent reports describing cytotoxic and anti-proliferative effects in various tumour cell lines.
Most oil contained significantly higher monoterpenes than sesquiterpene
, except oil from medium depth peatland where amount of sesquiterpenes
slightly higher (38.
